Be it known that I, C. SCIIWANER, of Keokuk, in thecounty of Lee, Stuteof Iowa, have invented a new Trace-Buckle; and I do hereby declare thefollowing to be afull, clear. and exact description thereof, referencebeing had to the accompanying drawings, making part of this specification, in Which- Figure 1 is a perspective view oithe improved buckleapplied to a trace and llame-strap.

Figure 2 is a view ol" the buckle detached from the straps.

Figure 3 is a longitudinal section through the improved buckle andstraps.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to a new and improved buckle, which is designedparticularly for the use of traces. It consists in the combination ot' astationary tongue or hinged clamp' so constructed as to afford a firmerhold and safer attachment than buckles which have hinged or pivotedtongues, as will be hereinafter described. I To enable others skilled inthe art to understand my invention, I will describe its construction andoperation.

In the accompanying drawings, A represents a rectangular clumpingframe,which is secured to the hametug B; and C represents that portion ofthebuckle-frame which has the tongue formed on it,l'and through which thetrace-strap D is passed. This frame C has a tongue or stud, e, formedupon its outer surface, near its pivoted end, and in the middle of itswidth, which tongue is slightly'taperng, and of such length as to passthrough the holes which are made through the trace, as shown in fig. 3.The free end of the frame C is curved outward sufficiently to allow thetrace to lie atly against the transverse portions ff when passed throughthis frame, as

shown in fig. 3. TheV frame A, to which frame C is pivoted, isconstructed of .the curved form shown in igs. I, 2, and 3, with aflattened transverse clamping-ba.r, g, which extends across the frame C,so as to press upon the trace D in rear of' and near the tongue e. Thisframe A is pivoted to frame C, and constructed in such manner that whenthe trace is under tension the bar q will be iorcibly pressed againstthe trace, and thus serve, in conL junction with the tongue e on frameC, to firmly confine the trace. The clamping action of the bar q offrame A not only prevents the trace from slipping oii` the tongue e, butalso gripes the trace in rear of this tongue, so that enlargement ortea-ring out of the trace at the holes is prevented. i

It will be seen from the above description that I'have a trace-buckle,which consists of but two parts, pivoted together and so formed as toafford a combined tongue and clamp-fastening for straps. The buckle isalso so constructed as to admit of a ready attachment and detachment ofthe trace when it is not under tension.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

The manner substantially as herein described and shown of constructingand arranging the two curvedhinged frames constituting the buckle, incombination with clamp g and holding-tongue e.
